Review decision

To resubmit, address

1. Correct the outcome-class classification for sources: move Rinne 2024 to 'mechanistic/animal' (not cardiometabolic); move Senderovich 2023 to 'cognition' (not cardiometabolic); re-tabulate the corpus accordingly.
2. Reframe GuijarroHernandez 2026 explicitly as a C. elegans mechanism study and remove claims about human 'longest-lived fasting-versus-control contrast' since the underlying source explicitly states ADIOL 'does not extend lifespan.' Restrict longevity claims to mechanistic plausibility.
3. Resolve the conflict between the Abstract's claim that Caristia 2020 'found no consistent healthy-aging benefit' and the Caristia 2020 bundle excerpt showing positive anthropometric and cholesterol findings. Either qualify the abstract statement as 'no consistent healthy-aging benefit beyond weight/BMI/cholesterol surrogates' or remove it.
4. Replace or substantively fill the 'Key Findings' section with 3–5 actual key findings (with their supporting source citations), rather than outcome-class boilerplate.
5. Tighten the Conclusion by collapsing redundant restatements of the same evidence-tier caveat; aim for 2–3 bounded paragraphs.
6. Audit and correct the apparent fabrication of the submission directory timestamp in the Search Summary, or remove the timestamp if it is unverifiable.
7. Verify whether Tal 2025 belongs in the synthesis given its ovarian-cancer-specific focus; if retained, clarify why it is in 'contextual_other' rather than a clearly unrelated oncology slice.
8. Match the reporting framework labels in the Methods/Search Summary (PRISMA-ScR vs 'rapid evidence synthesis' article_type) and remove the mismatch.

Major issues

• Self-contradictory year/study handling: The Search Summary claims the manuscript uses PRISMA-ScR structured scoping synthesis, yet the piece itself repeatedly states it is a rapid evidence synthesis (article_type) and is reported in adjacent terms. The reporting framework is inconsistent across sections.
• Several statistics appear to be sourced from a C. elegans preprint misattributed to 2026 (GuijarroHernandez 2026): lifespan/healthspan p-values (P < 0.0001, P < 0.001, P = 0.001) are presented as if from a human cohort, but the cited source is a C. elegans mechanism paper that explicitly states 'ADIOL does not extend lifespan, indicating its healthspan benefits are independent of longevity.' The synthesis treats the model-organism data as a longevity cohort, which is a category error and a material miscoding of evidence tier/direction.
• The manuscript labels Rinne 2024 as 'cardiometabolic' when it is a male-mouse bone/marrow adipocyte study; it does not measure cardiometabolic endpoints. This misclassification is propagated into the cardiometabolic results discussion.
• Senderovich 2023 is classified as 'cardiometabolic' but the source bundle shows it is a cognition review that includes DASH and other diets; pairing this as cardiometabolic evidence inflates the cardiometabolic corpus.
• Tal 2025 (ovarian cancer genomic signature) is classified as contextual_other, which is defensible, but no direct linkage to caloric restriction outcomes is supported by the source — the synthesis nonetheless treats it as relevant context without explaining the mechanism.

Minor issues

• Several sections rely on p-value lists attributed to specific sources without grounding in the supplied bundle excerpts; bundle excerpts either do not contain those p-values or are not annotated with them. Per reference-only calibration, default to assuming the numbers are accurate, but the synthesis should mark such numbers as 'per source registry' rather than presenting them as text.
• Abstract reports Caristia 2020 'found no consistent healthy-aging benefit' and Senderovich 2023 'P < 0.05 cognitive signals only in selected sub-domains.' The Caristia 2020 excerpt actually reports several positive findings on weight, BMI, fat mass, total cholesterol. The synthesis later contradicts the abstract's framing, producing an internal inconsistency.
• The 'Key Findings' section is essentially empty, containing only outcome-class boilerplate and no actual key findings. This degrades the manuscript's usability.
• Search Summary references a submission directory timestamped 2026-07-01 (e.g., synthesis-caloric_restriction_fasting_effects-v06-DAILY-2026-07-01T12-18-05Z-R2) which looks like a fabrication anchor; this should either be sourced or removed.
• The Conclusion is appropriately bounded but overlong and repetitive; the same caveat is restated in nearly identical paragraphs.
• Source-context map subtitle says 'Oncology and cancer context: 1 sources' (singular/plural mismatch).
• Direct evidence tally ('0/13 admitted source(s)') in Gaps contradicts the corpus tables that include several review-level sources that are direct in their domain; the '0 direct' framing is acceptable only if consistently defined across sections.

Reviewer note

## Rapid Synthesis Review **Triage:** Revise. **Scope and audit trail:** The Search Summary is admirably explicit for a rapid synthesis — it lists multiple databases, search strings, eligibility criteria, a candidate funnel with exclusion buckets, and supporting artifacts (methods_pack.json, manifest.json, gate files). This is a clear strength and earns a 4 on research_question_quality. **Source grounding:** The 13-source bundle is largely recent (2020–2026), accurately traced to the manuscript prose, and consistently supports the bounded claim that cardiometabolic surrogates move favorably while hard clinical/longevity endpoints remain unproven. Two issues prevent a 5: 1. **GuijarroHernandez 2026** is a *C. elegans* mechanistic paper stating that ADIOL "does not extend lifespan, indicating its healthspan benefits are independent of longevity." The synthesis treats its p-values (P < 0.0001, P < 0.001, etc.) as a human longevity cohort signal — a category error. The longevity claim needs to be re-bounded to mechanistic plausibility only. 2. **Rinne 2024** and **Senderovich 2023** are miscoded into the cardiometabolic class, which inflates that domain's evidence count without warrant. Per the rubric's reference-only calibration, the p-values are assumed accurate, but source/direction mismatch remains a separate defect. **Claim-evidence alignment and overclaim:** The Conclusion is appropriately bounded and explicitly disclaims clinical/policy/causal claims — good. However, the Abstract's claim that Caristia 2020 "found no consistent healthy-aging benefit" partially contradicts the bundle excerpt, and treating the C. elegans paper as human longevity evidence is a mild overclaim. Net: partially supported, mild overclaim. **Synthesis quality:** The framework (endpoint-sensitivity gradient, evidence-tier hierarchy, cross-source disagreement maps) is genuinely useful and integrates evidence rather than listing it. But the false-positive longevity signal undermines the integration. Score 3, leaning to 4 once the miscoding is fixed. **Limitations:** Specific and material: the manuscript explicitly notes that conclusions cannot cross single-source slices, that direct evidence is absent, and that adherence gates long-term effects. This earns a 4. Adding a sentence about outcome-class miscoding would lift to 5. **Gaps:** The Gaps section identifies the right next-step trials (long-duration RCTs, prespecified endpoints, standardized exposure), which is good. Score 3 because it reads as a generic checklist; concrete prespecified endpoints (mortality, incident disability, MACE) and adherence-support designs could be named more explicitly. **Decision:** The manuscript is mostly correct and salvageable with bounded edits — primarily outcome-class recoding, removal of the C. elegans-mislabeled longevity p-values, and fixing the empty Key Findings section.
